f vTo all whom it may concern: y'

A,Be it known that L'ELWIN H. BooNnY, a citizen of the United States, residing in Vhitinsville, Massachusetts, have invented the following-described new and useful Improvements in Comber Feed-Roll Motions.

The invention relates more lparticularly to the feed motion of Heilmann type combers and its object is to improve the eX- tent and character ofthe overlap and generally to promote the efiiciency of the comber and also to simplifythe drive mechanism of the feed rolls whereby the first `cost and also the cost of upkeep and the care ofsuch mechanism is reduced.

The invention consists in the construction exemplified by the structure shown in the drawings forming partherein and detailed 4in the following description Figure 1 of the drawings is a partial top plan of the driving mechanism of a Heilmanncomber with certain well understood parts removed. Fig. 2 is an enlarged end elevation of the` feed roll gearing shown in Fig. 1. Fig. 3 is a rear elevation of the same gearing on enlarged scale. Fig. 4 is a detail. Fig. 5 is a sectional view on line 5-5 of Fig. 2 and' Fig. 6 is a crosssection of one of the combing heads of a Heilmann type comber. f Referring first to Figs. 1 andl 6, the comber Vtherein illustrated comprises the -usual series of frame uprights 1, which divide and support the several combing heads of the machine and the uprights 2 and 3V which formrthe support of the various parts of the driving mechanism. The roll of lap to be combed is carried upon the pair of lap roll rollers 4, shown in Fig. 1, and bv them passed over Aan apron 5, part of which only is shown in Fig. 6, into the nip of the feed rolls 6 and 7, by which the lap is supplied to the nipner mechanism. The upper feed roll 6 is held against the lower roll 7 bv a pair of arms, as indicated and which are under spring .pressure (not shown). The lower roll 7 is mounted or formed as usual on a continuous shaft 8 common to all the combing heads of the machine and extending therefrom into the space between the uprights 1 and 3, which space and the uprights therein form the drive head of the comber. The nipper mechanism comprises a pair of alternately openng, .and closngwjaws 9.and1`0 vactuated by Specification of Letters Patent.

COMBER FEED-ROLL MOTION.

Application led February 5, 1912. Serial No. 675,468.

the connections shown, which, when open, allow the lap to move therethrough to a desired eXtent and when closed, nip and hold the lap while the half lap 11 on the comb- `ing cylinder acts upon its projecting end.

After this end or tuft has been thus combed 1t is pressed by the detaching segment 12 againstthe lower side of the detaching roll 13 and thereby separated or detached from the body of the lap and passed forwardly into the piecing rolls 14 and 15, where it is overlapped or pieced on the tail end of the previously combed and detached tuft in the usual way and thence passes out through the pan 16 as a continuous sliver, as will be well understood.

The combing cylinder is mounted on a Comb shaft 17, which like the feed roll shaft 8 is also common to all the combing heads,

`as will be understood, and extends from the latter into the drive head above referred to where it is liournaled in each of the frame uprights and driven by its index Vwheel 18 from the drive pinion 19 on a primary drive shaft 20. 17a being an ordinary shaft coupling. "lt will, of course, be understood by those skilled in this art that the drive head of the comber includes Vmany other parts which may be also driven by the same drive shaft for operating the nipping and piecing side of the said upright which is nearest tov the combing heads. On the opposite side of the upright the comb shaft is supplied with a bevelpinion 22 and between the worm wheel and pinion is a train of gearing through which the comb shaft drives the feed roll shaft. This train is of the constant motion type, that is to say, consists wholly of spur or worm teeth or both together, arranged to impart the motion of the comb shaft to the feed roll'shaft with no change except as to the speed ratio. As the comb shaft rotates continuously and at a constant rate, it follows that the feed roll shaft willalso rotate at a constant rate and continuously by reason ofthe use of ,thetype sof of gearing train referred to. The feed rolll shaft, thus constantly and continuously ro tated, is connected at its opposite end with the gearing and shafting shown in dotted lines and marked 23 in Fig. 1 whereby it drives the lap roll rollers above referred to so that the lap unwinding from the lap, roll when, on the opening of the nippers the tuft is drawn forward in the detaching operation.

The train of gearing above referred to comprises in its organization a change-speed mechanism by which the rate of the feed roll motion may be altered. More specifically the said train consists of a bevel pinion 24 which meshes with the bevel pinion 22 and is fast on a short shaft 25, which latter shaft carries a small pinion 25 in mesh with a larger idler spur gear 27, the later being mounted on an adjustable stud 28. Through this idler the comb shaft motion is imparted toa pinion 29 on a worm shaft 30, the worm 31 of which meshes with and drives the worm wheel 21 above referred to. The worm shaft 30 is disposed on the combing head side of the frame upright 2, being journaled in a bracket-bearing 32 which is separately shown in Fig. 4 and which is adjustably secured to the side of the upright by means of a bolt 33 and a suitable oblong slot. The

adjustment o f the bracket 32 accommodates the adjustment of the position of the feed 'roll shaft, the bearing 3 4 of which is adjustably bolted to the inclined upper edge of the frame upright. The shaft 25 and the stud 28 of the idler gear are carried on a Separate bracket secured to the opposite side ofthe said upright and preferably by the same bolt 33 which for this purpose extends through the head 2a of that upright. The shankportion 35 of the latte-r bracket is car- -Ccpies of this patent may be obtained for ve cents each, by address Washington, D. 03g

V28 of said idleris adjustably secured. Such slot 39 isl preferably arcuate and concentric with the axis of the shaft 25 and Where it approaches the shaft 25 the latter is fenestrated as shown at 40 'to provide access to the nut of the stud 28 in any' position that such stud may occupy in the arcuate'jslot. The pinion 29 is a change'gear, being attached to its worm shaft so that it can beA M readily removed and replaced by another change gear of different size, the `axis of the idler 27 being shifted accordingly so that any desired rate of feed roll motion, i. e.

any extent of lap feed per combing nip of V:so

the machine canthus be obtained.. i

1. In a Heilman comber, the combination of the lap feed'rolls and including a feed tional movement to said feed rolls,` and a train of continuous motion gearing for drlvroll shaft, the nipperand piccing mechanisms f' land the combingv cylinder shaft, of means for advancing a continuous lap witha unidirecing the feed roll shaft and'adapted Vtoirn-V Y' part continuous motion to the 'feed rolls without severing the said lap( 2. A Heilman comber comprising nipper 'mechanism including. alternately opening and closing jaws, and combing and piecing means coperating therewithin combination with lap-supplying means in rear 'of'sai'd jaws comprising one or more lap-advancingmembers each rotating onlyin a `forward direction, andthe advancingmember which is immediately in 'rear 'ofv such jaws having. a continuous forward motion.
